The sum of the measures of the interior angles of a 47-gon is ___ degrees.

The possible dimensions of the rectangular garden are 8ft by 12ft, 6ft by 16ft, and 4ft by 24ft

In this problem, Misaki used five sections of fencing, two 4 ft sections, two 6 ft sections, and one 8 ft section to build a rectangular garden without cutting any. To find the possible dimensions of the garden, we can use the lengths of the fencing sections to make different combinations of the length and width of the garden.

Here are a few possible combinations for the rectangle shaped garden.

A garden that is 8 ft by 12 ft: This would use the two 4 ft sections as the width and the two 6 ft sections as the length.

A garden that is 6 ft by 16 ft: This would use the two 4 ft sections as the width and the one 8 ft section and two 6 ft sections as the length.

A garden that is 4 ft by 24 ft: This would use the two 6 ft sections as the width and the one 8 ft section and two 4 ft sections as the length.

It's important to notice that there are no other possibilities with the given lengths of fencing. Misaki can't have different dimensions because all the lengths are given, and if the width and length are swapped, we will get a different rectangular garden.

Step-by-step explanation:

f(x) = x² + 5 g(x) = x + 4

for f(g(x)) or (f○g)(x) we take the expression of g and place it everywhere in the expression of f where x is mentioned.

so, (x + 4) goes into (x² + 5) giving us

((x + 4)² + 5) = x² + 8x + 16 + 5 = x² + 8x + 21

so, (2) is the correct answer.

8.

the same principle

f(x) = 2x + 9 g(x) = (x - 9)/2

just here we take f and put it into g :

g(f(x)) = ((2x + 9) - 9)/2 = 2x/2 = x

so,

(a) g(f(15)) = 15

(b) g(f(-3)) = -3

(c) g(f(x)) = x

to verify e.g. (a) we use x = 15 in f(x)

f(15) = 2×15 + 9 = 30 + 9 = 39

and then we use this result as new x = 39 in g :

g(39) = (39 - 9)/2 = 30/2 = 15

correct.

Step-by-step explanat

By taking the quotient between consecutive terms we can see that it is constant, thus, the sequence is geometric.

A geometric sequence is a sequence where, to get the next term, we need to multiply the previous term by a constant number.

The general recursive formula for a geometric sequence is:

Aₙ = c*Aₙ₋₁

Where c is a constant.

The given sequence is:

500, 100, 20

If we take the quotient between two consecutive terms, we will get:

100/500 = 1/5

20/100 = 1/5

We got the same denominator in both equations, then we can write:

100 = 500*(1/5)

20 = 100*(1/5)

So we have the previous term times a constant, which s 1/5, so this is a geometric sequence.

Answer: 23 percent

23 percent of attendees supported the home team.

The percentage of people supporting the home team is 22.98%.

Percentage is a way to express a fraction or proportion as a relative quantity out of 100. It is often denoted by the "%" symbol. It's used to compare and represent quantities, such as discounts, proportions, or rates, in a more easily understandable form. To find the percentage of people who supported the home team, we need to divide the number of people supporting the home team by the total number of people attending the game and then multiply by 100.

Therefore,

Calculating the percentage of people supporting the home team -

= (Number of people supporting the home team / Total number of people attending) x 100%

Substituting the values -

= (667 / 2900) x 100%

= 667/29

Answer:2.5:1

Step-by-step explanation:

Hi there! So already noticeable, there are some given parts and pieces.  AD is unknown, and BC it seems is also unknown, since they are both congruent to each other.  Segment AB is twice the length of AD, and AB is parallel to BC.  DC is 4 cm longer than AB.  

If you've done proofs, here's one thing that can help: Angle ADC and BCD are congruent to each other by same-side interior angles theorem.

If you haven't done proofs, I'm just going to keep this a little bit more understandable.  I don't want to overload you with a million formulas/theorems.

AD = BC
AB = 2(AD)
AB || BC
DC = AB + 4

Wait a minute... :)

AD x 2 = AB.  AB is 4 units shorter than DC.  

Try making an equation.  AD can be x, AB can be y, and DC can be z.

2x = y
y + 4 = z, z - 4 = y

2x = z - 4

So try substituting in some things that can work.  The length of AB has to be 2 times the length of AD.  DC is AD + 4.  AD can be 2, AB can be 4, and DC can be 8.  

2(2) = (8 - 4)
4 = 4 :)

Looks like it works! You should probably ask your teacher/parents for help with this one, it looks a little odd.  But that's the best I can do for you.  :)

the total number of deer in the park can be expected to be less than two years old 360.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, Park rangers tagged 80 deer in a park they found that 24 of the deer were less than two years old.

The number of deer that are less than two years old:

=> 1200 * 24/80

Since the ratio of the deer is 24/80

=> 1200*3/10

=> 360

Answer: 5148 can be expressed as a product of prime factors using power notation. To find the prime factorization of 5148, we can divide it by the smallest prime number that divides it until the quotient is a prime number.

5148 = 2 * 2574

2574 = 2 * 1287

1287 = 3 * 429

429 = 3 * 143

143 = 11 * 13

So the prime factorization of 5148 is:

5148 = 2^2 * 3^3 * 11 * 13

Therefore, 5148 can be expressed as a product of prime factors using power notation as 2^2 * 3^3 * 11 * 13.

Step-by-step explanation:

Answer:2² x 3² x 11 x 13

Step-by-step explanation:

5148 - This is divisible by 9 as the sum of digits is 18 which a multiple of 9.

5148/9 = 572

572 is divisible by 4 as the sum of last two digits is a multiple of 4.

572/4 = 143  

143 is divisible by 11 and 13.

So, the factors are 4 x 9 x 11 x 13 or 2² x 3² x 11 x 13

A function is an equation that has a single solution for each value of y.

When two functions f and g share a domain and a codomain, and f(a)=g is true for each an in the domain, we say that the two functions are equal (a).

A function is an equation with just one solution for every value of y in the equation. A function pairs each input of a particular type with exactly one output. Instead of y, it is typical to name functions f(x) or g(x).

If two functions share the same domain and codomain as well as the same values across the board, then they are considered to be equal.

In spite of how the elements are arranged in the sets, two sets are said to be equal when all of their components are present in both. Afterward, the sets are referred to as equal sets. When all of one set's elements are absent from the other, two sets are said to be unequal.

The value of cos(45°) is 1√2. The solution is obtained using properties of a right angled-triangle.

What is a right angled-triangle?

A right angled-triangle is a type of triangle whose one angle is 90° and the remaining two angles add up to 90°, thus, making the sum of the angles equal to 180°. The prolonged side of the triangle is known as hypotenuse.

The right triangle's three sides are connected to one another. The Pythagorean Theorem explains how these two things are related.

Base^2 + Perpendicular^2 = Hypotenuse^2

We are given length of one side equal to 6.

We know that sin 45°= Opposite side/Hypotenuse= 1/√2

Therefore, the hypotenuse will be 6√2.

Using Pythagoras theorem, we get

(6√2)^2= 6^2+ Perpendicular^2

72-36= Perpendicular^2

Perpendicular= 6  

We know that for cosine, it is adjacent side/hypotenuse.

Since, the adjacent side is 6 and the hypotenuse is 6√2,

Cos(45°)= 6/6√2 = 1√2

Hence, the value of cos(45°) is 1√2.

Using matrices the value of y is calculated to be -2

A determinant is a square array of numbers or variables surrounded by vertical lines.

This method is applied by first solving the determinant of the problem

D = 2 * 6 - 2 * 7

D = 12 - 14

D = -2

Solving for y

Replace the second column with the column at the right side of the equality sign. Solve the determinant in this condition and divide with the first determinant D = -2

Δ = (2 * 6) - (2 * 4) = 12 - 8 = 4

y = Δ / D

y = 4 / -2

y = -2
